Acid rain stone

Abstract

The invention discloses a component formula and a preparation process of an acid rain stone. The acid rain stone comprises the components by weight percentage as follows: 30-50% of zeolite, 65-45% of (zeolite and sulfuric acid), and 5% of (zeolite,hymexazol and plant growth regulator). The process flow comprises the following steps: step A, adding zeolite particles in a cement pool, then, filling 93% sulfuric acid, dipping for 60min, taking out and placing on an impermeable cement ground, and airing to obtain a product A; step B, filling zeolite particles in another cement pool, placing 30% hymexazol water aqua and DA-6, naphthyl sodium acetate, and sodium heteroauxin mixture; agitating while filling, and dipping for 150min; then, taking out and placing on the impermeable cement ground, drying in shade to obtain a product B; and step C, compositing the products A and B and zeolite in different proportions to obtain the acid rain stone product which is quantitatively packaged and bagged.

Description

technical field [0001] The invention relates to a group of saline-alkali land improvement products with the effects of "strong salt reduction, quick-acting alkali removal, and deep denitrification", which belongs to a new type of saline-alkali soil improvement agent. Background technique [0002] For thousands of years, farmers have used organic fertilizers (farmyard manures) to provide comprehensive and balanced nutrition for crop growth, but organic fertilizers are slow to produce fertilizers. For decades, agricultural production has switched to chemical fertilizers with rapid fertilizer effects. Although sufficient nutrients such as nitrogen, phosphorus, and potassium have been supplemented, it has caused soil compaction and soil fertility to decline. In the past ten years, in order to overcome the disadvantages of using chemical fertilizers, farmers have begun to use organic-inorganic compound fertilizers, or biological bacterial fertilizers that have the functions of ni...

Problems solved by technology

Using 30-40 tons per hectare of gypsum products to improve saline-alkali land to plant rice has obvious effects, but there are two disadvantages at the same time: one is that the supply of products exceeds demand, and the other is that it is extremely inconvenient for farmers to use large quantities

Using furfural slag to improve saline-alkali land also has the same effect, and the same disadvantages
